Patented dan. i949 UNITED STATES PATENT o'I-FlcE s claims.` (ci. 248-26) The vpresent invention relates to a motor support, and in particular to one providing a resilient mounting for anelectric motor, or the like, involving a minimum number of parts and 5 a maximum facility of assembly.

The invention in brief consists of a base member having resilient opstanding ends into which the outer rings of a resilient motor bearing are cradled and latched.

lo It is an object of the invention to provide such a motor support wherein 'the resilient ends may l readily be snapped over parts of the motor hubs and latched into position.

It is a further object of the invention to prold vide a motor support wherein means are employed flexibly to mount the motor and involving unbroken annular rings with resilient shock absorbing material, such as rubber, and which rings are adapted to latch into the upstanding elem ments of the base.

In the drawing: Y

Fig. l is an elevation of the motor support, the motor being shown in dotted lines;

Fig. 2 is a plan view of the support;

2li Fig 3 is an end View with the motor removed;

Fig. Ll is a vertical section on the line il--ll ci lille. 2;

Fig. 5 is a vertical section on the line 5-5 of Fig. 2; and

till l'lg. 6 is a vertical section on the line li-t of Fig. 3.

The motor is shown at lt and includes the usual hub members l l and i2 with a rotor shaft lil.

The base member is generally indicated at lt and includes a iiat section l5 adapted to be rested upon a suitable foundation and bolted thereto if desired by bolts it. Holes i'l in the portion l5 receive the bolts.

lll From the opposite ends of the portion l5 extend upwardly the supports I8 and I9 that are made of such material as to be slightly resilient so that they may be moved toward or away from each other, but will resiliently return to their #it normal vertical positions.

EachV end member is provided with a cradle 20 that may be of any suitable shape, such as semioctagonal. Each end member likewise has stamped out therefrom lugs 2l for a purpose to 50 be described.

Around the two motor hubs are tightly secured inner rings 22. Concentrically arranged with these inner rings are anged outer rings 23. Between each ring 22 and 23 is located a pad of 5s resilient material 2l, this material preferably being live rubber. The anges of the rings 23 are designated at 25.

Within the flanges 25 are located a series ot openings 26 that are spaced apart the same distance as that between the two stamped out lugs 5 2| on the standards lb and l9.` Four holes 26 are provided, although ordinarily two are suicient. In use, the resilient ring mountings consisting of the inner ring 22, the outer ring 23, and the padding 24, are put in position over the mol0 tor hubs, the flanges 25 being away from the motor. The rings 22 tightly engage the hubs ll and l2 of the motor. 'I'he motor is then set down between the standards I8 and I9 of the base member I4, the standards being adapted to w tit closely behind the two iianges 25. The motor will be lowered between the two standards until the outer rings 23 are cradled within the cradles 20 on the standards. 'I'he flanges 25 will pass over the lugs 2l and, in so doing, will displace 2u the standards i8 and I9 inwardly, which is permitted by the inherent resiliency of the said standards. The holes 26 will then come opposite the lugs 2i, whereupon the said lugs will be snapped outwardly by the resiliency of the stand- 2b ardsY to engage in the holes.

With this arrangement, the vibrations from. the motor are, to a large degree, absorbed by the rubber 2t. The motor is tightly held because the standards i3 and i9 fit snugly back of the iiangcs dit 25 and, if desired, may exert some outward pressure against these flanges, such pressure insuring a lack of noise between the contacting elements. The weight of the motor holds it in the cradles 2li and it is prevented from being withdrawn .liti therefrom by the action of the lugs 2l within the holes 2li. However, when it is desired to remove the motor, such may easily be done by flexing the standards i8 and I9 inwardly so that the lugs 2i will be clear of the holes 26.

It will be seen that the foregoing motor support is adapted for quick assembly and disassembly. It :further is inexpensive and permits the use of solid and not split ringresilient mountings.

In the event that the motor is mounted on a. wall, a pair of holas 26 on the side of the iiange 25 may be employed. In this ease the motor may partly be supported by the lugs 2|. The motor may also be suspended from the ceiling, in which 50 case the two top holes 26 are used; and the motor is then supported entirely` by the lugs 2l, and prevented from lifting by the cradle 20.

Consequently, in the appended claims, it is imderstood that the phraseology is intended to cover Il mounting the motor either on the iioor. wall, or ceiling. 1

What is claimed is:

1. In a motor mounting, a pair oi.' spaced, resilient standards. an open-ended cradle on each of the standards, to receive and support the hubs of a motor, and snap-acting means operable by displacement of the standards to hold the motor in place within the cradles.

2. In a motor mounting, means to support one end of a motor. a resilient standard adjacent the other end, a anged member on the motor, the iiange being adapted to lie alongside the standard, and snap-acting means engaging between the resilient standard and the iange to hold the motor in place, said means being rendered operative by deflection of the standard.

3. In a motor mounting, means to support one end of a motor, a resilient standard adjacent the other end of the motor, said standard having means to support its end of the motor, said motor and standard, when in operating position, having contiguous surfaces, the standard surface being urged toward the motor surface by the resiliency of the standard, and interengaging means on said two surfaces preventing Withdrawal of the motor.

4. In a motor mounting, means to support one end of a motor, and a resilient standard adjacent the other end, said standard having means to receive and support a motor, said motor and standard having contiguous surfaces, one of said surfaces having a lug outstanding toward the other surface, the said other surface having a recess to receive the lug, the lug being engageable in the recess upon exing of the standard to part the surfaces, the lug holding the motor onto the support.

5. In a motor mounting means to support one end of a motor, "a resilient standard adjacent the other end, said standard having a cradle to receive the hub assembly of the motor to support that end of the motor, the hub assembly having a ange spaced from the motor and adapted to lie outside the standard, the standard having a surface lying against the flange and maintained there by the resiliency o! the standard, and snapacting means including a lug and a recess interengaging between the ilange and the standard to resist removal o! the motor from the standard.

6. In a motor mounting, hub assemblies on opposite ends of the motor, each assembly including a resilient ring, a rigid ilanged ring surrounding the resilient ring, a pair of standards at least one of which is resiliently movable relative to the other, said standards having cut-outportions in 10 which the hub assemblies are received, and snapaction means between each hub iiange and its adjacent standard to retain the motor on the standards.

7. In a motor mounting, a base, a pair oi reagainst the standards with the ring cradled in the same, a pair of lugs struck out from each standard, and a pair of holes in each flange, the said lugs being snapped into the holes by dis' placement of the standards, and being adapted removably to prevent withdrawal of the motor from the free side of the standards.

8. In a motor mounting, a base, a pair of standards on the base, means supporting one end of the motor on one standard, the other standard having a hub-receiving cradle open at one end, the hub of the corresponding end of the motor having therearound a resilient pad, a

' rigid member surrounding said pad and adapted to enter the open end and rest in the cradle on the standard, the rigid member having a ange extending from the cradle contiguous to a surface oi the standard, and readily separable interengaging means between the ange and said surface to prevent withdrawal of the hub from the cradle.
